Currently, I have finished interviewing my high school students to learn about their demotivating and remotivating factors. I'm trying to use case-study method to analysis data. In my understanding, I think I should treat each of my students as a seperate case and do a cross-case analysis like Rober Yin said in his book. I'm wondering if my understanding of cros-analysis is correct. I plan to create a table to display each students' factors and to see if there's any pattern. At the present, I see that there is some connection between their English proficiency and their factors, so I decides to classify my students into groups according to their level of proficiency. My question is how report this findings. Should I report the similar factors of all groups first according to each category and then describe those unique to each group?
